AED carb I bought brand new and it’s only been run on my drag car. 440 540 cam, 3000lb and ran between7.10-25. Bolted it on like it came and it ran beautiful. Adjustable air bleeds. This is way above a run of the mill Holley. Swapped it out last year for an 850 and it was a pretty much a waste of money. List on this carb is $689. Asking $575 and I’ll ship it to the lower 48. Thats right $575 shipping included. Paypal
